This book has it all. It's mathematically accurate, highly informative, up-to-date, and beautifully written. In addition, Carlson's anecdotes of high-roller life in the casino fast lane make for a really fun, entertaining read. Carlson is both a mathematician and a successful high-stakes Blackjack player, and he presents the concepts behind card counting in an easy-to-understand way that is accurate, informative, and practical. This book is just chock full of priceless information. It presents the theory of card counting, basic strategy, game selection, camouflage, casino comportment, special "commando" tactics, money management, risk of ruin, etc., etc., as well as Carlson's own Advanced Omega II System, which all the experts agree is the strongest BJ system going. AOII is a level-2 card-counting system that I've found easy to learn and easy to use. And it works! It really gets the money. K-O and Hi-Lo don't come close. This book is the bomb! If you could only have one book on BJ, this should definitely be it. Highly recommended.
